A soil profile consists of 2m of sand (γ=18kN/m³, kv=4 x 10-2m/day) over 3m of silt (γ=17kN/m³, kv=1 x 10-2m/day) over 2m of silt (γ=16kN/m³, kv=5 x 10-4m/day) over gravel. The water table is 0.5m below the ground surface. A piezometer placed at the top of the gravel layer measures a porewater pressure of 42kPa. Assuming a one-dimensional flow condition in the vertical direction, compute the flow rate in m³/day/m². Also compute, atmiddepth of the clay layer, the porewater pressure, total vertical stress, and effective vertical stress.

A 9.15m thick layer of sandy soil overlies an impervious rock. The groundwater level is at a depth of 1.22m below the top of the soil. Water was pumped out of the soil from a central well at the rate of 5680 kg/min and the drawdown of the water table was noted in two observation wells. These two wells were on a radial line from the centre of the main well at distances of 3.05m and 30.5m.
